Abstract: Systems and methods for enhanced directionality for portal detector stations are provided. The systems include a portal detector station, an overhead detector station, a controller operatively coupled thereto. In embodiments, the controller analyzes read events detected by the portal detector station to determine a set of RFID tags included in a pallet of objects. The controller also analyzes read events detected by the overhead detector station to determine a direction of travel for the RFID tags included in the set of RFID tags and/or to detect stray read events that resulted in RFID tags being erroneously included in the set of RFID tags.
